Full-Hard (H04) C16500 Copper

H04 C16500 copper is C16500 copper in the H04 (full hard) temper. It has the second lowest strength and second highest ductility compared to the other variants of C16500 copper. The graph bars on the material properties cards below compare H04 C16500 copper to: wrought coppers (top), all copper alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
